[I've looked in the mail archives and couldn't find a solution....] I'm running 4.3-STABLE from mid-July. When I boot, I get the following error: sio1: configured irq 3 not in bitmap of probed irqs 0 Now according to the BIOS, the second serial port is set for 0x2F8 and IRQ 3 (and enabled). [This port works under Windows] Nothing else is using IRQ 3. If I boot verbose, I get: sio0: irq maps: 0x201 0x601 0x201 0x201 sio0: <3COM PCI FaxModem> port 0xec00-0xec07 irq 10 at device 19.0 on pci0 sio0: moving to sio2 sio2: type 16550A sio0: irq maps: 0x241 0x251 0x241 0x241 sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 16550A sio1: configured irq 3 not in bitmap of probed irqs 0 sio1: irq maps: 0x241 0x241 0x241 0x241 sio1: probe failed test(s): 0 1 2 4 6 7 9 sio1 failed to probe at port 0x2f8-0x2ff irq 3 on isa0 What am I doing wrong and how do I get this port recognized?
